I want a search that must be very common: return topics best suited to a search.
The topic document has the topic title (and perhaps other fields)
The children docs are the posts in the topic, and they have several fields the most important is the post itself.
I don't want the search to return children individually, only parents.
I want to score the search by balancing topic title to a score relative to the post body.
And the whole thing should be filterable on such things as date ranges, users post, message board name, etc (attributes of the children or attributes of the parent)
Having trouble getting this simple thing to work: to return only parents ordered by best match. based on their text and the text in their children....
